Task Scheduler alternative

Question

Task Scheduler alternative

Matthias 25

Hi there,

Microsoft's task scheduler is not reliable ( do not take my word for it, just search for "Task Scheduler did not launch task xyz as it missed its schedule. Consider using the configuration option to start the task when available, if schedule is missed" ).

There are a ton of posts on several platforms. Many of them are years old.

So is there an alternative to "task scheduler"?

Answer 1

Is the task set to "Run only when the user is logged on" or "Run whether the user is logged on or not"? Your xml file does not have a <LogonType> attribute in it.

Does your get_status_of_services.bat need to access any network resources? That is, does it build some report file and save it to a file share on a different server? Or does it only access local resources?

If you're just monitoring (or restarting) services, you may want to consider running the task as the SYSTEM account instead of a domain account.

Your task is set to "run a bat file". I would recommend that you set it to run cmd.exe with the /c (Carries out the command specified by string and then terminates) switch. That should insure that cmd.exe terminates after the bat file completes. I have also found it useful for troubleshooting to capture stdout and stderr.

I believe that your issue is related to the fact that you set both the "Recur every" and "Repeat task every" settings along with the duration of Indefinitely.

For a task that monitors services every 5 minutes, I would suggest these settings. I don't see any value in the 30 second randomization.

Also enable task history, and monitor Next run time, and Last run result.

changing "for a duration of: 1 day" seems to solve the problem.

But it is counterintuitive to me. I want a task to run every 5 minutes.
That is easy in cron (as soon as You read the documentation for 1 minute) :
*/5 * * * * /script.sh
In Windows, I have to run that task every day AND every 5 minutes each day.

The GUI would be clearer that way (at least to me):

You should be able to schedule a task to run one time, and then set the repeat duration to indefinitely. Pick any date in the past for the Start.

Hi Matthias.

This behavior typically occurs when the system is unavailable at the scheduled time and the task isn’t configured to “Run as soon as possible after a scheduled start is missed.” Enabling that option often resolves most reliability issues.

If you’re looking for alternatives, there are a few options depending on your use case. For Windows environments, PowerShell scripts combined with Windows Services or Azure Automation can provide more robust and cloud-managed scheduling. If you’re working in a mixed or server-based environment, Azure Logic Apps, Azure Functions (with timer triggers), or System Center Orchestrator are great enterprise-grade solutions for task automation and reliability.

I hope this information is useful. Thank you

The system(s) are not connected to the internet. So, cloud-based workarounds (azure) are not an option.

It is really frustrating, that MS does get this fixed for years.

But there is a new development regarding my issue:

The task is still not running, but now without any error or warning.
Task Scheduler displays "next run time", the time passes and nothing happens.
There are just no changes in the "history" tab.

I can try to help if you want.

Can you export the task and save it as an XML file. Then open the XML file with notepad and remove any sensitive information. For example, if the task is set to run as a domain user, just put a placeholder like "MyDomain/MyUser" where your real user is identified.

Then save it as a .txt file and attach it to a comment here. I'll play with it and see if I can find anything.

Is your machine up and running at the task scheduled run time, or was it shut down or rebooting at that time?

What OS are you running?
